Study type: Medical/biological study (experimental study)

DEXA analysis on the bones of rats exposed in utero and neonatally to static and 50 Hz electric fields. med./bio.

Published in: Bioelectromagnetics 2006; 27 (7): 589-592

Aim of study (acc. to author)

To study the influences of 50 Hz and 0 Hz (static) electric fields on intact rat bones.

Background/further details

Animals (n = 27) are continuously exposed in utero and neonatally to electric fields (10 kV/m) 14 days before and 14 days after their birth.

Main outcome of study (acc. to author)

The data have shown that both static electric fields and 50 Hz electric fields influence the early development of rat bones. However, static electric fields caused more significant amounts of change (decrease) in bone mineral content and bone mineral density as compared to the 50 Hz electric fields.
